How Does the Concept of “Unspent Transaction Output” (UTXO) Relate to a Miner’s Revenue?
A UTXO is the remaining amount of cryptocurrency from a transaction that can be spent. When a transaction is created, the sender consumes one or more existing UTXOs and creates new ones.
The difference between the total value of the consumed UTXOs and the total value of the new UTXOs (plus the change returned to the sender) is the transaction fee. This fee is what the miner collects as part of their revenue for including the transaction.
